FABRIC-CUTTING- DEVICE.

To all whom 'it may concern.' I I Y Y Beit known that ANDERS L. BERTHEL- SEN, a lsubject. ofthe King of Denmarlnrresiding at Chicago, in the county of Cook andv State o-f Illinois, haveV invented certain new and useful Improvements in rvFabric- Cutting Devices, ofwhich the followingis The present 'nvention'relates to improvements in fabric cutting devices, the cutting operation of which is produced by a rela- A tive movement between the fabricl andthe cutter, as distinguished from a Yscissorsraction. Among others, the objects of the invention are to provide a relatively smallor pocket size article embodying a cuttingblade disposed within ,cloth guiding means so arranged withV 4regard to the edge Yof the blade as to produce a vmovement of the fabricA in a direction at an angle to said -edge to .therebysever the material along the desired line of cut; to provide the guiding means aforesaid in the form of a sheath which constitutes a protector for the blade, and manipulative means for the device; and to provide holding means for thc blade so coacting with the sheath as .to hold the inaterial fin proper alinement in advance of the guiding means preliminary to severing and enabling the blade to be variably ,adjusted for presenting Ya new cutting edge when desired.

These and such other objects as may hereinafter appear are attained by the novel construction, combination, and arrangement of parts to be hereinafter specifically described and claimed. Reference will now be had to the accompanying drawings forming a part of thisV specification, wherein:

blade holder by meansof which construc- 1rtion the blade is adjusta-bly held 'by the holder and capable of' adjustment invia longitudinal direction aswell as reversibile adjustment. In other words, thej blade is preferably of a type embodying a yseries of .g;

cutting edges and said blade may be shifted inthe longitudinal direction forthe purpose of changing the portion of the edge of the blade with relation to the cloth guiding means hereinafter described whereby longer life and use of the blade is secured. It will be obvious that the said blade may be reversed so that the'rearportion of the upper edge may be disposed in the operative position, above referred to or the blade maybe 1 inverted and thesame adjustment, ofthe previously lower edge securedt In Fig. 3 of the drawing is indicateda slightly modified form ofblade 5, suchobvioiis modification of the cutter r1'element being within the purview of this invention. The holder l -is disposed within a case or sheath 6 somewhat oval incross section, said 'holder bongmovablelongitudnally into such .sheathj fro-mytheV rear end so thaty its -fronti or .g.

4. In a vcutting device of the class described, a blade, a holder therefor and a sheath in which said holder is movably received, the sheath having guide means at one end spaced from the edge of the blade and projecting substantially in advance thereof to preliminarily act upon the material prior to cutting action and subsequently move said material in a direction across the edge upon relative movement between the material and the cutter.

5. In a cutting device of the class described, a blade, a holder therefor and a sheath in which said holder is movably received and including fabric guiding means, said sheath having gripping means with which the holder is slidably engaged and held in operative relation to the guiding means aforesaid.

6. In a cutting device of the class described, a blade, a holder therefor and a sheath in which said holder is movably received, said sheath being slotted at one end to form spaced fabric guiding means and gripping means coperative with the holder.

7. A fabric cutting device comprising a blade, a sheath substantially entirely sur` rounding said blade, said sheath having an opening exposing a point of the cutting edge of the blade, and into which opening fabric or the like may be introduced to contact with said point, and blade holding means within the sheath on which the blade is adjustable to and fro to shift the cutting point along the blade edge when the latter becomes dull at any particular point.

8. In acfabric cutting device, the combination of a blade, a sheath in which said blade is housed, a holder sustaining the blade within the sheath and having an end portion thereof projecting exteriorly of the sheath to constitute fabric supporting and guiding means for directing the fabric into the sheath into contact with the blade, and means on said sheath cooperative with the projecting portion of the blade holding means whereby to preliminarily fold the material about said means as the fabric moves relatively into the sheath for severance by the blade.

9. In a cutting device of the class described, the combination of a sheath, a blade mounted in said sheath, a holder for said blade for sustaining the same in operative position in the holder comprising coperative sections between which the blade is clamped, the end of said holder projecting from the sheath to coperate with the fabric in the movement of the latter into cutting relation with respect to said blade.

10. In a cutting device of the class described, the combination of a sheath, a blade mounted in said sheath, a holder for said blade for sustaining the same'in operative position in the holder comprising coperative sections between which the vblade is clamped, the end of said holder projecting from the sheath to coperate with the fabric in the movement of the latter into cutting relation with respect to said blade, and means on the sections of the holder with which the blade is adjustably engaged for providing for shifting of the blade to effect a change of the cutting point along the edge of said blade.

11. In a fabric cutting device, a blade, a sheath, fabric guiding means on said sheath, and means providing adjustment of the blade with relation to the guiding means and for retracting the blade from the sheath.

12. In a fabric cutting device, a blade, a sheath cut out at one end to form spaced guiding and gripping means, and a blade holder, the walls of the sheath forming the gripping means being pressed inwardly to slidably engage the holder.

13. In a fabric cutting device, a blade, means for holding the blade in operative position exposing a point of the cutting edge to material to be cut, and means within the holding means permitting adjustment of the blade along the longitudinal aXis of said holding means to change the cutting point.

14. In a fabric cutting device, blade holding means and a reversible blade bodily aoljustable to shift the eective cutting point of the cutting edge in a longitudinal direction.

15. In a fabric cutting device of the class described, a blade, manipulative means therefor, and relatively stationary means for supporting the material to be cut while the point of severance thereof moves relatively toward the blade preliminary to cuttino.

1&6. A fabric cutting device of the class described comprising a cutting element, and means arranged in advance of Said cutting element to preliminarily act upon the mate` rial to be cut to effect folding of the same prior to cutting action, and guide means with which the projecting portion of the holder coacts to force the material against the edge of the blade.

In testimony whereof I afliX my signature.
